科大銀河級打手 2017-4-15 12:22:06 marking 8b 寫錯左
Term of trade果到0.75D寫左做0.75T

割家他 2017-4-15 12:24:42 預留下午做上面份mock

11e
should be MB>MC

改乜名好呀 2017-4-15 12:48:23 想問下當the world economy is weakened嘅時候 exports自然會跌啦咁但係點解imports又會冇變

:^(

一個國家唔係應該都會受影響令到國內經濟都差左 c跌 m跌架咩？

有個問題困擾左我好耐求解答
當D升 P升Q升
TSS一定升啦
PS都一定升
咁到底CS自己既change 係升定uncertain

:^(
:^(

CS increases.
You need to use the new equilibrium point (new MB=new MC) as a reference.
You would see both CS and PS increase.

Cs not necessarily increase
Cs= summation of mb-p
Mb increase and price increase as well
Effect of cs can be uncertain

:^(

同埋冇人話過一定要係parallel shift
:^(

DSE題目會寫明假設parallel shift ge

應該唔會出not in parallel manner嘅

12d係咪寫錯regressive做progressive

i think yes

no
assume all people are rational

割家他 2017-4-15 14:25:44 How about Q5a
More people buy electric cars-> competitive demand-> d of diesel cars decreases-> q and p both decrease

Rationality 2017-4-15 14:26:21 Sorry太趕寫個marking好多錯
改翻先

割家他 2017-4-15 14:32:06

How about Q5a
More people buy electric cars-> competitive demand-> d of diesel cars decreases-> q and p both decrease

substiute既解釋係一邊P跌demand for substiute跌
electric cars P升係因為demand升左
所以要係supply個邊諗

Rationality 2017-4-15 14:42:07 既然係咁我出番份pdf version比頭先做過既4位巴絲啦

你地有無email?

btw thanks頭先講問題既巴打，尤其銀河兄應該上左岸

我記得唔知邊個老師既mock係出過non-parallel
好似係cliff sir，有無巴打證實下

讓風箏飛. 2017-4-15 14:49:50 點解marginal benefit curve= demand curve? 好驚佢問依d問題岩岩做完rationality 巴打份mock 發覺自己唔係好熟mc=supply mb=demand 個d點解釋?

Rationality 2017-4-15 15:12:29 有無submit左既巴打要pdf answer?
